Fm'med integral with around the wheel between the hub and the felly. ,l/Vhen said wheel is in use and travels over the ground, the inner portion .or the disks 1 will slide vertically a short distance relatively to the outer ring 9, and owing to the connection of these two parts by the Pa rs of flexible sections a resilient cushion.- ing effect is produced which is in every way similar to the result obtained by the use of a wheel having a pneumatic tire. The ring 9 cannot become detached from between the outer edges of the disks 1 and the downward limit of movement of said disks relatively to the ring 9 is limited by the inner edge of said ring 9 coming in contact with the shoulders "attire inner end of the space 7. Should either of the pairs of sections and id become punctured while the wheel is in use so as to render it inoperative, a number of the screws 18 may be removed from the retain- 'ingr.ings 17 to allow bolts to be inserted through the corresponding apertures 8 and '14, thus locking the ring" 939 the disks 1, and said wheel will thus be made temporarily serviceable until the punctured sections 15 and 16 can be replaced by new sections.

A pneumatic wheel of my improved construction is simple, strong, and durable,

easily assembled or taken apart, and is applicable for use on all classes of vehicles.

It will be readily understood that the flexi ,35"-b,l,e sections 15 and 16 may be replaced by a i sin le thickness of flexible material.

I claim.

1. ,A pneumatic wheel, constructed with a pair of disks rigidlyjixed together, there be mg an annular space formed between the vOuter-edges of the disks, a ring arranged to slide in the annular space between the outer edges of the disks, a felly integral with the ring, a tire carried by the felly, there being grooves formed in the outer faces of the felly and there bein grooves formed in the outer faces of the dis s, inflatable flexible sections arranged on each side of the disk and felly in such a manner as that portions of said flexible sections occupyt'he grooves in the disk and felly, and retaining-rings clamped uponthe disks and felly overithe edges of ghelinfiatable sections; substantially as specie 2; A ,neumatic wheel, constructedwith a pair of disks rigidly fixed togethenthere being an annular space formed betweenthe outer ed es of the disks, a ring arranged to slide in t e annular space between the outer dges of the disks, the interior diameter of which rin is less than the exterior diameter of the dis s, a felly integral'with the ring, a tire carried by the folly, there being grooves formed in the outer faces of the felly and there being grooves formed in the outer faces of the disks, inflatable flexible sections ar-- ranged on each side of the disk and felly in such a manner as that portions of said flexible sections occupythe grooves in the disk and folly, retaining-rings clamped upon the disks and felly over the ed es of the inflatable ,seetibns, and meansw 'ereby air under pressure is delvered through the disks between the inflatable sections; substantially asspecified. i
